[`pyupgrade`] Fix parsing named Unicode escape sequences (`UP032`) (#21901)

## Summary

Fixes https://github.com/astral-sh/ruff/issues/19771

Fixes incorrect parsing of Unicode named escape sequences like `Hey
\N{snowman}` in `FormatString`, which were being incorrectly split into
separate literal and field parts instead of being treated as a single
literal unit.

## Problem

The `FormatString` parser incorrectly handles Unicode named escape
sequences:
- **Current**: `Hey \N{snowman}` is parsed into 2 parts `Literal("Hey
\N")` & `Field("snowman")`
- **Expected**: `Hey \N{snowman}` should be parsed into 1 part
`Literal("Hey \N{snowman}")`

This affects f-string conversion rules when fixing `UP032` that rely on
proper format string parsing.

## Solution

I modified `parse_literal` to detect and handle Unicode named escape
sequences before parsing single characters:
- Introduced a flag to track when a backslash is "available" to escape
something.
- When the flag is `true`, and the text starts with `N{`, try to parse
the complete Unicode escape sequence as one unit, and set the flag to
`false` after parsing successfully.
- Set the flag to `false` when the backslash is already consumed.

## Manual Verification

`"\N{angle}AOB = {angle}°".format(angle=180)` 

**Result**

```bash
 def foo():
-    "\N{angle}AOB = {angle}°".format(angle=180)
+    f"\N{angle}AOB = {180}°"

Would fix 1 error.
```

`"\N{snowman} {snowman}".format(snowman=1)`

**Result**
```bash
 def foo():
-    "\N{snowman} {snowman}".format(snowman=1)
+    f"\N{snowman} {1}"

Would fix 1 error.
```

`"\\N{snowman} {snowman}".format(snowman=1)`

**Result**
```bash
 def foo():
-    "\\N{snowman} {snowman}".format(snowman=1)
+    f"\\N{1} {1}"

Would fix 1 error.
```

## Test Plan

- Added test cases (happy case, invalid case, edge case) for
`FormatString` when parsing Unicode escape sequence.
- Updated snapshots.
